Questions and Answers

What is the primary responsibility of a collection?

  • To provide various traversal algorithms
  • Efficient data storage (correct)
  • To manage complex data structures
  • Efficient data retrieval
  • Why should traversal algorithms not be added to a collection class?

  • Because they are too complex to implement
  • Because they are not compatible with all data structures
  • Because they are not necessary for data storage
  • Because they blur the primary responsibility of the collection (correct)
  • What problem arises when client code is coupled to specific collection classes?

  • The code becomes more efficient
  • The code becomes harder to understand
  • The code becomes tightly coupled to the collection implementation (correct)
  • The code becomes more flexible

    Study Notes

    Collections in Programming

    • A collection is a container for a group of objects, storing elements in simple lists or complex data structures like stacks, trees, and graphs.
    • Collections must provide a way to access their elements for other code to use them.
    • Accessing elements in a collection involves traversing them sequentially without repeating any elements.

    Traversal Algorithms

    • Traversal algorithms are needed to access elements in complex data structures like trees.
    • Different traversal algorithms are required for different scenarios, such as depth-first, breadth-first, and random access.
    • Adding multiple traversal algorithms to a collection class can blur its primary responsibility of efficient data storage.
    • Some algorithms may be specific to certain applications, making it unsuitable to include them in a generic collection class.

    Collection Classes and Client Code

    • Client code may not care about how collections store their elements, but it must couple with specific collection classes due to varying access methods.
    • This coupling limits the flexibility of client code to work with various collections.
